IMPROVEMENT IN PEED+ROLLERS FOR LAMP-WIGKS.

TO ALL WHOM IT MAY CONCERN:

Be it known that 1, CHARLES H. BAGLEY, of Elgin, Kane county, in the State of Illinois, have invented a new and improved Feed h'lcehanism for Lamps, $90.; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanyingdrawings, forming part of this specification.

The present invention relates to a'uorel manner of constructing a feed-roller, cylinder, or-drum ofthat class of feed-rollers which is provided with a series of spirally-arranged teeth or prongs; and the invention consists in making such rollers or cylinders of a strip of sheet, metal or other suitable material, provided with a series of teeth or prongs along one or both of its edges, that are bentup at an angle, either more or less great, to the body of the strip, by spirally winding such strip'abcut a ccntrcmandrcl or core, or in any other suitable manner, which, bringing its teeth in a spiral line or lines around a cylinder thus produced, forms it suitable for use as a means of feeding wicks in coal-oil and other lamps, and for other analogous purposes, and wherever such rollers will be found serviceable. In the accompanyingdrawings my improved feed mechanism for lamps" is illustrated-- v Figure 1 Plate 1, being a side view of a wick-tube'having it applied thereto.

Figure 2, Plate 1, a transverse vertical section taken in the plane of the line a: a, fig. 1, plate 1.

Figure 3, Plate 2, a plan or top view of a strip of sheetmctal provided with teeth along one of its edges, and before being spirally wound;

Figure 4, Plate 2, an edge view of the strip shown in fig. 3, but with the teetlrbent up; and

Figure 5, Plate 2, a plan or top view of a roller or drum, made according to the present invention, with the several coils of the spiral loosened.

Similar letters of reference indicate corresponding parts. i

In the drawings my improved construction of afeed-roller is shown as adapted for use in coal-oil lamps, and therefore in the following description willbc explained more particularlyin reference thereto.

A, in the drawings, 1 and 2, represents a wick-tube having an opening, B, made in and across one of its sides, C. In this opening, from end to end, is hung a cylinder or druu1,D, to turn in bearings at each end of the ear-pieces E in the wick-tube. This cylinder or drum D is the feed-cylinder to the lamp-wick, and is constructed from a narrow strip or band of sheet metal of any suitable kind, or other proper material, which,

along one or both of its edges, is provided with a series of teeth or prongs marked a in the-figures of the two plates 1 and 2 of the drawings. These teeth are first bent up at an angle more or less right, to the body or main portion of the strip or hand; when, taking such strip, it is spirally wound around any suitable centre, core, or mandrel, from one end tothe other, or for any-part of its length, according to the length of cylinder or drum, thereby producing a-cylinder or drum, with a series of spirally-arranged teeth or prongs around its periphery. In winding the sheet-metal strip to form it into a cylinder or drum, its coils may be more -o-r less close or open, and for supporting and strengthening itafter being thus wound, it may be filled with, and soldered or otherwisc fastened to, any suitable core or centre, and in the case of a f cedu'ollcr for lamp-wicks it is secured to a centre spindle, F, that being extended out through the side of the lamp-top is at its outer end provided with a milled head, Gr, suitable for turning it. It may be here observed that as the teeth to the feed-cylinder extend around in a spiral direction, each tooth works upon thewick in a distinct path of its own, whereby its most perfect operation is insured.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A toothed or pronged roller, drum, or cylinder, made from a strip or strips of sheet metal or other suitable material, provided with teeth along one or both of its edges, and spirally wound into the fornnof a cylinder or other equivalent sha pe, substantially as and for the purpose described.
